One automobile manufacturer recently outfitted a test-pilot as an empty driver’s seat in order to gauge public, man-on-the-street reaction to autonomous vehicles, not so much for the rubbernecking effect that driverless car illicit but rather a means to study how such cars might signal their intentions and how quickly traditional vehicles and pedestrians sharing the road might pick up on that newly minted language. Presently drivers get a lot of mileage out of a tap of the horn or flashing high-beams but apparently a more sophisticated system is needed to interact with human controlled traffic. While some useful data was gleaned off of the stunt, the methodology reportedly was not the best.
